Refer to IMS/SIP - Basic Procedures if you want to know more. Client port (port-c) is 5100 and server port (port-s) 6100.

The successful calls were made with a commercial eNB (in his case a Casa smallcell), while srsENB the ACK takes a very long time to reach the UE, resulting in disconnected calls.įrom the screenshot, we see a UE that supports IPSec got a response from S-CSCF, indicating that ipsec-3gpp is supported, protocol is ESP (ethernet proto 50, IPSec). Herle Supreeth has shared PCAP files of successful calls, including that you need to run P-CSCF as root, in order to add xfrm state and policy. If there is an NAT between PGW and P-CSCF, IPsec-NAT would not work, and the PCAP looks like the one below. If the port if not open, or DNS is not properly configured, the phone cannot reach P-CSCF and fails. When DNS is not properly set, you may end up with 478 Unresolvable destination (478/SL): PCAP files of successful calls can be found on VoLTE Setup. If you don’t know what CoIMS is, please refer to step 23 of VoLTE Setup. On your cellphone, there should be internet and ims.ĬoIMS should look like the one below. Thanks to Open5GS, the topology is super similar to SAE on Wikipedia. You might have leading or trailing spaces in FHoSS, resulting in failed connections! 7. FHoSS will automagically convert it to hex. Step 20, add IMS subscriptions to FHoSS.įor already running systems, copy SQN from Open5GS and type it in FHoSS.Kamailio does not support VoLTE over IPv6 at the moment. Important! Set the type of both APN to IPv4. Step 18, set IMSI, Ki, OP, SQN and APN of your SIM cards.
